ANTIOCH — A man who was swinging an ax-like weapon at people on a popular trail was arrested Friday afternoon, police said.

The suspect, who appeared to be under the influence of drugs, crashed his truck into two vehicles near Lone Tree Way and James Donlon Boulevard, then ran to the Delta De Anza Regional Trail where he was reported swinging an ax and a box cutter at people, according to an eyewitness.

After police responded to the area, located near the Sutter Delta Medical Center, the man held the box cutter to his neck and jumped over a fence, the witness said. He was hanging off the fence until he was pepper sprayed by officers and fell into a nearby canal.

Antioch police did not reply to requests for comment Friday afternoon.

The suspect then swam to the other side of the canal before being pulled out of the water, the witness said.
